Contrast-Enhanced Ultrasound-Guided Endoscopic Retrograde Appendicitis Treatment-A Pilot Study on the Diagnostic and Therapeutic Efficacy in Uncomplicated Appendicitis. JOURNAL OF ULTRASOUND IN MEDICINE : OFFICIAL JOURNAL OF THE AMERICAN INSTITUTE OF ULTRASOUND IN MEDICINE 2024. [PMID: 38943425 DOI: 10.1002/jum.16515] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Subscribe] [Scholar Register] [Received: 03/29/2024] [Revised: 05/29/2024] [Accepted: 06/06/2024] [Indexed: 07/01/2024]
Abstract
OBJECTIVE To determine the diagnostic and therapeutic value of contrast-enhanced ultrasound-guided endoscopic retrograde appendicitis treatment (ERAT) in patients with uncomplicated appendicitis. METHODS A retrospective analysis was performed on clinical and ultrasound data collected from 105 pediatric patients with uncomplicated appendicitis between January 2020 and December 2023. The ultrasound findings before and after treatment, as well as postoperative follow-up and recurrence rates, were summarized and analyzed. RESULTS Successful intubation was achieved in 96 patients (91.4%). The conventional ultrasound appendix visualization rate was 39.6% (38/105), while the appendix visualization rate after contrast-enhanced ultrasound-guidance was 75% (72/105). Contrast-enhanced ultrasound revealed various appendiceal morphologic changes in 89 patients, such as twisting, tortuosity, stiffness, rough inner wall, dilated diameter, and narrowing of the lumen. Additionally, local filling defects, which indicated the presence of fecal stones or debris deposition, were noted in 68 patients. No leakage of the contrast agent occurred. Post-treatment evaluation showed improvement in appendiceal diameter, lumen, and filling defects (P < .01). The follow-up rate was 82 of 89 patients (92.1%), all of whom recovered well without a recurrence. The recurrence rate was 7.9% (7/89). Among the patients with recurrences, five patients resolved after medical treatment and two patients recovered after surgical treatment. CONCLUSION Contrast-enhanced ultrasound-guided ERAT for uncomplicated appendicitis is safe and effective. Specifically, the appendix is increased, which facilitates an evaluation of therapeutic effectiveness. ERAT serves as a valuable supplementary modality to determine the need for surgical treatment of acute appendicitis, which is of significant clinical value.

Abstract
The contrast-enhanced ultrasound (CEUS) has been mainly applied to adults to differentiate benign and malignant renal lesions, however, the characteristics of CEUS in pediatric has not been as well studied as in adults. In the present work, the eligible pediatric patients who underwent renal CEUS between March 2016 and February 2023 were retrospectively analyzed. It included 20 lesions (median diameter, 8.4 cm; range, 1.8-18.0 cm) from 20 patients (median age, 28.0 months; range, 3.0-212.0 months; 9 boys) in malignant group and 5 lesions (median diameter, 3.8 cm; range, 1.3-7.5 cm) from 5 patients (median age, 25.0 months; range, 0.7-216.0 months; 2 boys) in benign group. The diagnostic performance was assessed. Nonparametric and Chi-square tests were performed. With hyperenhancement plus wash-out, CEUS showed a sensitivity of 95.0% [95% confidence interval (CI): 75.1%, 99.9%], a specificity of 80.0% (CI: 28.4%, 99.5%), a positive predictive value of 95.0% (CI: 75.1%, 99.9%) and a negative predictive value of 80.0% (CI: 28.4%, 99.5%). It suggested that CEUS is a valuable technique for identifying between malignant and benign renal lesions in children.

Sutarjono B, Kessel M, Alexander D, Grewal E. Is it time to re-think FAST? A systematic review and meta-analysis of Contrast-Enhanced Ultrasound (CEUS) and conventional ultrasound for initial assessment of abdominal trauma. BMC Emerg Med 2023; 23:8. [PMID: 36703099 PMCID: PMC9881326 DOI: 10.1186/s12873-023-00771-4] [Citation(s) in RCA: 3] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/10/2022] [Accepted: 01/02/2023] [Indexed: 01/28/2023] Open
Abstract
BACKGROUND The Focused Assessment with Sonography for Trauma (FAST) examination using conventional ultrasound has limited utility for detecting solid organ injury. Therefore, this systematic review and meta-analysis compares the performance of contrast-enhanced ultrasound (CEUS) to conventional ultrasound when used as the initial assessment for abdominal trauma prior to computed tomography (CT) imaging. METHODS A systematic literature search of major databases was conducted of human studies investigating the diagnostic accuracy of conventional ultrasound and CEUS occurring prior to CT imaging for abdominal trauma. The study followed the PRISMA (Preferred Reporting Items for Systematic Reviews and Meta-Analyses) statement. The quality of studies was evaluated using the QUADAS-2 (Quality Assessment of Diagnostic Accuracy Studies 2) tool. Paired pooled sensitivity and specificity between conventional ultrasound and CEUS were compared using data extracted from the eligible studies. Diagnostic odds ratio, number needed to diagnose values, and likelihood ratios were also determined. RESULTS Ten studies were included. More than half of the included studies demonstrated low risk of bias. Using McNemar's test to assess for paired binary observations, we found that CEUS had statistically higher sensitivity (0.933 vs. 0.559; two-tailed, P < 0.001) and specificity (0.995 vs. 0.979; two-tailed, P < 0.001) than conventional ultrasound in the setting of abdominal trauma, respectively. When divided into particular findings of clinical interest, CEUS had statistically higher sensitivity than conventional ultrasound in screening for active bleeding and injuries to all abdominal solid organs. CEUS also had superior diagnostic odds ratios, number needed to diagnose values, and likelihood ratios than conventional ultrasound. CONCLUSION The diagnostic value of CEUS was higher than that of conventional ultrasound for differentiating traumatic abdominal injuries when used as the initial assessment in the emergency department.

Abstract
PURPOSE Intra-abdominal injury is a major cause of morbidity in children. Computed tomography (CT) is the reference standard for the evaluation of hemodynamically stable abdominal trauma. CT has an increased risk of long-term radiation induced malignancies and a possible risk associated with the use of iodinated contrast media. Contrast-enhanced ultrasound (CEUS) might represent an alternative to CT in stable children with blunt abdominal trauma (BAT). Nonetheless, CEUS in pediatrics remains limited by the lack of strong evidence. The purpose of this study was to offer a systematic review on the use of CEUS in pediatric abdominal trauma. METHODS Electronic search of PubMed, EMBASE and Cochrane databases of studies investigating CEUS for abdominal trauma in children. The risk of bias was assessed using the ROBINS-I tool. RESULTS This systematic review included 7 studies. CEUS was performed with different ultrasound equipment, always with a curvilinear transducer. Six out of seven studies used a second-generation contrast agent. No immediate adverse reactions were reported. The dose of contrast agent and the scanning technique varied between studies. All CEUS exams were performed by radiologists, in the radiology department or at the bedside. No standard training was reported to become competent in CEUS. The range of sensitivity and specificity of CEUS were 85.7 to 100% and 89 to 100%, respectively. CONCLUSION CEUS appears to be safe and accurate to identify abdominal solid organ injuries in children with BAT. Further research is necessary to assess the feasibility of CEUS by non-radiologists, the necessary training, and the benefit-cost ratio of CEUS as a tool to potentially reduce CT scans.

Abstract
The diagnostics and treatment of pediatric urology patients in the clinical routine can be extremely challenging. In comparison to adult patients, congenital diseases, more time consuming examinations and limited options in addition to the parents' expectations must be taken into account in the diagnostic work up. In this first of two parts we will delve into ultrasound diagnostics as the cornerstone in the diagnostic pathway of children with hydronephrosis ans take a closer look on contrast enhanced ultrasound (CEUS). Conventional voiding cystourethrography still plays a major role in the diagnostic pathway of vesicoureteric reflux and will be treated in this article. Computed tomography should only be considered in pediatric patients in rare cases, always taking radiation into critical account. Magnetic resonance imaging provides an excellent anatomical overview without exposing the child to unnecessary radiation. This article provides an overview on the diagnostic imaging studies in pediatric urology and brings tips for the diagnostic evaluation.

Abstract
Cranial US is an integral component of evaluating the neonatal brain, especially in the setting of critically ill infants and in the emergency setting, because cranial US can be performed portably at the bedside, is safe, and can be repeated whenever needed. Contrast-enhanced ultrasound (CEUS) involves intravenously injecting microbubbles to allow for improved visibility of large and small vessels to assess vascularity and is becoming a widespread technique to improve diagnostic performance of US across a broad spectrum of applications. CEUS has the potential to add value to routine brain US and become a useful adjunct to MRI in infants in need of bedside imaging. In this review we describe the basics of US contrast agents and CEUS technique, including safety considerations, and detail the potential clinical uses of brain CEUS.

Abstract
BACKGROUND Glomerular disease, including immunoglobulin A nephropathy (IgAN) and Henoch-Schönlein purpura nephritis, is one of the most common kidney diseases in children. The diagnosis of these diseases depends on pathological biopsy, although this procedure is seriously limited by its invasive and high-risk nature. OBJECTIVE To investigate the potential of contrast-enhanced ultrasonography (CEUS) for evaluating the histopathological severity of IgAN and Henoch-Schönlein purpura nephritis (HSPN). MATERIALS AND METHODS We investigated a total of 13 children with IgAN and 12 children with HSPN confirmed by renal histopathology. We reevaluated the pathological lesions of the children according to the Oxford classification and the Lee grading system and then all the children underwent CEUS. Using SonoLiver software, we constructed time-intensity curves of CEUS for regions of interest in the renal cortex. We analyzed CEUS quantitative parameters for IgAN and HSPN and used Spearman correlation analysis to examine the correlation between CEUS parameters and clinicopathological indexes in the study cohort. RESULTS The CEUS parameters rise time (RT) and time to peak (TTP) were significantly higher in children with Lee grade IV than in those with Lee grades II or III. Spearman correlation analysis revealed a positive correlation between rise time and time to peak with Lee grade in the overall cohort of children, and a positive correlation between rise time and time to peak and severity of crescents in the Oxford classification scoring system. CONCLUSION Contrast-enhanced US may be used as a noninvasive imaging technique to evaluate the severity of renal pathology and formation of crescents in children with IgAN and HSPN.

Abstract
Introduction Contrast‐enhanced ultrasound (CEUS) is a widely used diagnostic method. In adults, it has been proven to be a useful alternative to CT and MRI for the characterisation of focal liver lesions (FLLs). However, since there is no official paediatric licensing for any ultrasound contrast agents in Europe, its use has been restricted. Purpose To retrospectively outline our experience with CEUS as a tool for the characterisation of FLLs in paediatric patients. Methods An eleven‐year retrospective single‐centre study. During this period, we identified 287 CEUS examinations performed on children, of these 36 were relevant first‐time examinations with the aim of characterising a focal liver lesion. Clinical and radiological data were collected from the hospital chart. Results The overall agreement between the CEUS diagnosis and the reference diagnosis for benign versus malignant differentiation was 75%. When analysing conclusive CEUS examinations only, the overall agreement was 96%. The specificity for correctly characterising a lesion as benign was 96%, and the negative predictive value was 100%. No side effects from CEUS were detected. Conclusions Our study reinforces that CEUS can be useful in the medical workup for the identification and classification of focal liver lesions in children.

Abstract
Contrast-enhanced ultrasound (CEUS) has been increasingly used in pediatric radiology practice worldwide. For nearly two decades, CEUS applications have been performed with the off-label use of gas-containing second-generation ultrasound contrast agents (UCAs). Since 2016, the United States Food and Drug Administration (FDA) has approved the UCA Lumason for three pediatric indications: the evaluation of focal liver lesions and echocardiography via intravenous administration and the assessment of vesicoureteral reflux via intravesical application (contrast-enhanced voiding urosonography, ceVUS). Prior to the FDA approval of Lumason, numerous studies with the use of second-generation UCAs had been conducted in adults and children. Comprehensive protocols for clinical safety evaluations have demonstrated the highly favorable safety profile of UCA for intravenous, intravesical and other intracavitary uses. The safety data on CEUS continue to accumulate as this imaging modality is increasingly utilized in clinical settings worldwide. As of August 2021, 57 pediatric-only original research studies encompassing a total of 4,518 children with 4,906 intravenous CEUS examinations had been published. As in adults, there were a few adverse events; the majority of these were non-serious, although very rarely serious anaphylactic reactions were reported. In the published pediatric-only intravenous CEUS studies included in our analysis, the overall incidence rate of serious adverse events was 0.22% (10/4,518) of children and 0.20% (10/4,906) of all CEUS examinations. Non-serious adverse events from the intravenous CEUS were observed in 1.20% (54/4,518) of children and 1.10% (54/4,906) of CEUS examinations. During the same time period, 31 studies with the intravesical use of UCA were conducted in 12,362 children. A few non-serious adverse events were encountered (0.31%; 38/12,362), but these were most likely attributable to the bladder catheterization rather than the UCA. Other developing clinical applications of UCA in children, including intracavitary and intralymphatic, are ongoing. To date, no serious adverse events have been reported with these applications. This article reviews the existing pediatric CEUS literature and provides an overview of safety-related information reported from UCA uses in children.

Although contrast-enhanced ultrasound has been shown to provide considerable benefits, particularly in pediatric patients, it is still used relatively rarely in Brazil. It has proven to be a safe technique, and adverse effects are rare. In this review, we address the technique and main applications of contrast-enhanced ultrasound in the pediatric population, including the evaluation of focal liver lesions, abdominal trauma, kidney grafts, liver grafts, bowel loops, and vesicoureteral reflux. It is important for pediatric radiologists to be acquainted with this promising tool, understanding its applications and limitations.

Abstract
Background: MRI is the gold standard for neonatal brain imaging but is expensive, time-consuming, potentially limited by availability and accessibility, and may be contraindicated in some patients. Transfontanelle neonatal head ultrasound is an excellent alternative but may be less sensitive and specific than MRI. Contrast-enhanced ultrasound (CEUS) has the potential to improve ultrasound's capabilities. Objective: To prospectively evaluate the feasibility, safety, and diagnostic performance of transfontanelle neonatal brain contrast-enhanced ultrasound (CEUS), using MRI as the reference standard. Methods: Neonates in the institutional neonatal ICU undergoing MRI as part of clinical care were prospectively recruited to undergo portable brain ultrasound and CEUS for research purposes. Brain ultrasound and CEUS were performed portably, without moving the patient from the isolette or crib in the NICU. Adverse events were recorded. Two radiologists independently evaluated ultrasound and CEUS images for abnormalities and then reached consensus for discrepancies. A separate radiologist reviewed MRI examinations. Sensitivity, specificity, and inter-reader agreement were evaluated, using MRI as reference. Qualitative post hoc image review was performed. Results: Twenty-six neonates (9 boys, 17 girls; mean age 15.2 ± 14.0 days) were included. No significant alteration in patient vital signs or adverse reaction to the ultrasound contrast agent (UCA) occurred. Mean examination duration was significantly shorter for CEUS than MRI (21 ± 4.7 minutes vs 74 ± 34.8 minutes, p<.001). Inter-rater agreement for any abnormality was almost perfect for both ultrasound and CEUS (k= 0.92 and 0.85, respectively). Sensitivity for any abnormality was 86.7% for ultrasound and 93.0% for CEUS; specificity was 100.0% for both. CEUS exhibited sensitivity of 87.5% for acute or subacute ischemia and 100.0% for chronic ischemia, and specificity of 100.0% for acute or subacute ischemia and chronic ischemia. Sensitivity for subdural and intraparenchymal hemorrhage was poor (22.2%-50.0%) at both ultrasound and CEUS. Post hoc review demonstrated a case of post-ischemic hyperperfusion, confirmed by subsequent contrast-enhanced CT, on CEUS but not on MRI. Conclusion: Portable brain CEUS in neonates is feasible, safe, and more rapid than MRI. Clinical Impact: The potential diagnostic utility of brain neonatal CEUS relative to conventional ultrasound, particularly for ischemia, warrants further investigation.

[PMID: 34043256 PMCID: PMC8640938 DOI: 10.1111/andr.13057] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2021] [Revised: 05/12/2021] [Accepted: 05/24/2021] [Indexed: 01/17/2023]
Abstract
Background Contrast‐enhanced ultrasound (CEUS) is a sonographic technique that increases the diagnostic accuracy of ultrasound and color Doppler ultrasound (CDUS) when studying testicular abnormalities. However, its role in clinical practice is still debatable because there are no accepted standards regarding how and when this technique should be used for patients with testicular disease. Objectives To perform a nonsystematic review of the current literature to highlight the strength and flaws of performing CEUS and to provide a critical overview of current research evidence on this topic. Materials and methods A thorough search of published peer‐reviewed studies in PubMed was performed using proper keywords. Results Strong enhancement of neoplastic lesions (both benign and malignant) during CEUS aids in differential diagnosis with non‐neoplastic lesions, which usually appears either nonenhanced or enhanced in a manner similar to that of the surrounding parenchyma. CEUS enhancement has a high predictive value in the identification of neoplastic lesions, whereas a similar or complete absence of enhancement may be interpreted as strong evidence of benignity, although there are exceptions. Literature on quantitative analysis is still scarce, though promising, particularly in distinguishing benign from malignant neoplasms. Furthermore, CEUS may be useful in many emergency situations, such as acute scrotum, blunt scrotal trauma, and focal infarction of the testis. Finally, CEUS can help increase the probability of sperm recovery in azoospermic males. Discussion and conclusion CEUS is a safe, easy‐to‐perform, and cost‐effective diagnostic tool that can provide a more accurate diagnosis in testicular lesions and acute scrotal disease. However, further studies with larger cohorts are required to refine the differential diagnosis between benign and malignant neoplasms. Finally, these preliminary results can instigate the development of innovative research on pre‐testicular sperm extraction to increase the chances of sperm recovery.

Abstract
Contrast-enhanced ultrasound (CEUS) utilization is expanding rapidly, particularly in children, in whom the modality offers important advantages of dynamic evaluation of the vasculature, portability, lack of ionizing radiation, and lack of need for sedation. Accumulating data establish an excellent safety profile of ultrasound contrast agents in children. Although only FDA-approved for IV use in children for characterizing focal liver lesions and for use during echocardiography, growing off-label applications are expanding the diagnostic potential of ultrasound. Focal liver lesion evaluation is the most common use of CEUS, and the American College of Radiology Pediatric LI-RADS Working Group recommends including CEUS for evaluation of a newly discovered focal liver lesion in many circumstances. Data also support the role of CEUS in hemodynamically stable children with blunt abdominal trauma, and CEUS is becoming a potential alternative to CT in this setting. Additional potential applications that require further study include evaluation of pathology in the lung, spleen, brain, pancreas, bowel, kidney, female pelvis, and scrotum. This review explores the implementation of CEUS in children, describing basic principles of ultrasound contrast agents and CEUS technique and summarizing current and potential IV diagnostic applications based on pediatric-specific supporting evidence.

Abstract
OBJECTIVES To analyze the contrast-enhanced ultrasound (CEUS) characteristics of pediatric patients with focal liver lesions (FLLs) and develop a pediatric liver CEUS criterion to improve the diagnostic performance of CEUS in differentiating pediatric benign and malignant liver lesions. METHODS Between March 2011 and May 2020, patients < 18 years who underwent CEUS were retrospectively evaluated. The CEUS characteristics of FLLs were analyzed. A pediatric liver CEUS criterion categorized as CEUS-1 to CEUS-5 was developed. The diagnostic performance of the criterion (i.e., sensitivity, specificity, PPV, and NPV) was assessed. Chi-square and Mann-Whitney tests were used. RESULTS After exclusion, the study included 130 lesions (mean diameter, 7.1 cm; range, 0.8-17.0 cm) from 130 patients (mean age, 36.0 months; range, 0.03-204.0 months; 74 boys). Hyperenhancement with washout in patients < 5 years or with early washout (≤ 45 s) was used to predict hepatoblastoma, with a sensitivity and specificity of 90.7% (95% confidence interval [CI]: 77.9%, 97.4%) and 93.6% (95% CI: 84.3%, 98.2%), respectively. Peripheral discontinuous globular hyperenhancement was used to diagnose hemangioma, with a sensitivity and specificity of 84.6% (95% CI: 65.1%, 95.6%) and 100% (95% CI: 95.4%, 100.0%), respectively. The rates of malignancies within the pediatric liver CEUS-1, CEUS-2, CEUS-3, CEUS-4, and CEUS-5 categories were 0.0%, 0.0%, 5.6%, 50.0%, and 96.1%, respectively. Besides, the incidences of hepatoblastoma in pediatric liver CEUS-3, CEUS-4, and CEUS-5 were 5.6%, 16.7%, and 67.5%, respectively. CONCLUSIONS The pediatric liver CEUS criterion is useful in differentiating benign focal liver lesions from malignancies, especially hepatoblastoma from hemangioma. KEY POINTS • Hyperenhancement with washout in patients <v5 years or with early washout (≤ 45 s) were used to predict hepatoblastoma, with a sensitivity and specificity of 90.7% and 93.6%. • Peripheral discontinuous globular hyperenhancement was used to diagnose hemangioma, with a sensitivity and specificity of 84.6% and 100.0%. • The rates of malignancies within the pediatric liver CEUS-1, CEUS -2, CEUS-3, CEUS-4, and CEUS-5 categories were 0.0%, 0.0%, 5.6%, 50.0%, and 96.1%, respectively.

Abstract
Contrast-enhanced ultrasonography (CEUS) is a relatively new imaging method for use in children. It is recognized as a safe and easily performed problem-solving method. A premature 10-day-old female infant experienced unusual persistent anemia. The diagnostic workup for the anemia included an abdominal ultrasound examination, which showed pathological formation in the left middle quadrant. MRI was used to further asses the lesion and showed a hypervascular lesion with necrotic areas rising from the left hepatic lobe, mainly showing the pattern that indicates an infantile hepatic hemangioma. Main differential diagnosis, hepatoblastoma, could not be excluded. The crucial examination used to differentiate was CEUS.
